Re: WARN http: snmehl_connect: connect failed to ... Connection refused (error = 111)

We finally resolved the issue by

https://bplnap11.dpsg.net:1158/em

instead of

http://bplnap11.dpsg.net:1158/em

I guess we can ignore those error messages in the emdctl.trc log file?

Anyway, I feel I am the Dumbest DBA Award winner for this week :)
